The level of reserve balances was quite low Averaged around $10 billion in 2006
Desk and Board staff forecast factors driving supply of and demand for reserves
Almost every day, conduct a repo operation to add enough reserves to hit the fed funds target rate Averaged about $5-10 billion per operation
As demand for currency grew, banks’ reserves would decrease and the Desk would add reserves through purchases of Treasuries (long-run) and repos (short-run)

Current level of reserves is around $2.7 trillion A 27,000% increase!
Little need to forecast factors driving supply of and demand for reserves each day
No need to conduct repo operations to set the supply of reserves to the desired level Relatively small-scale adjustments to the supply of reserves
might do little to move the fed funds rate Since 2008, the Fed can pay interest to banks on the
balances that they leave in their account with the Fed Interest on excess reserve (IOER) has been very low: 25
bps from 2009 to December 2015

Short answer: Because they have no choice Reserves are injected in the system when the Federal
Reserve purchases assets Reserves must be held by institutions that have a Fed
account Banks can redistribute the reserves among themselves
but cannot change the aggregate amount Except for turning reserves into currency
The analysis that follows is based on Keister and McAndrews (2009)
Why are banks holding excess reserves?
12
Before 2008: Low amount of reserves
Suppose there are two banks, A and B Balance sheets in normal times:
Reserves 10 Deposits 100 Reserves 10 Deposits 100Loans 50 Loans 130 Due toDue from Bank A 40 Bank B 40Securities 10 Capital 10 Securities 10 Capital 10
Bank A Bank B
Note: Interbank lending promotes the efficient allocation of resources
13
The “crisis”
Suppose Bank A is no longer willing to lend to Bank B May have concerns about credit risk or about its own funding
needs If Bank B cannot replace this funding, it must reduce lending
Reserves 10 Deposits 60 Reserves 10 Deposits 100Loans 50 Loans 90 Due toDue from Bank A 0 Bank B 0Securities 10 Capital 10 Securities 10 Capital 10
Bank A Bank B
14
Central bank response to the crisis
Suppose the central bank lends to Bank B The decrease in lending can be avoided This is the “lender of last resort” function of the central bank
Reserves 50 Deposits 100 Reserves 10 Deposits 100Loans 50 Loans 130 Due to
CB 40
Securities 10 Capital 10 Securities 10 Capital 10
Bank A Bank B
Note: total reserves are now $60, $40 of which are excess
The Central Bank’s policy is highly effective, even though it generates a large amount of excess reserves
15
Bank lending and reserves
But … isn’t there a sense in which the $50 of reserves in Bank A’s account are idle? Don’t excess reserves represent “unused capacity” in the
banking system? Suppose Bank A lends $20 to Firm X, which is a customer
Reserves 50 Deposits 120 Reserves 10 Deposits 100Loans 70 Loans 130 Due to CB 40
Securities 10 Capital 10 Securities 10 Capital 10
Bank A Bank B
No change in reserve positions!
16
Level of reserves is unrelated to bank behavior
Now suppose Firm X buys $20 in equipment from Firm Y Firm Y holds its account at Bank B
Reserves 30 Deposits 100 Reserves 30 Deposits 120Loans 70 Loans 130 Due to CB 40
Securities 10 Capital 10 Securities 10 Capital 10
Bank A Bank B
Reserves (and deposits) are transferred to Bank B Again, no change in total reserves
The total level of reserves is determined entirely by the actions of the central bank (almost) Reveal nothing about the lending behavior of banks

Key question: Can we raise interest rates with a large balance sheet?
To do so, we need to make reserves sufficiently valuable Banks must be willing to pay a high enough rate to borrow
reserves Two mechanisms: Make reserves sufficiently scarce—Plan around 2011 Give reserves a rate of return and rely on arbitrage—
Current plan
Monetary policy normalization

Reserves in June 2011
20
The FOMC’s Exit Strategy Principles from 2011 focused on draining and returning to reserve scarcity To begin the process […] the Committee will likely first
cease reinvesting some or all payments of principal on the securities holdings in the SOMA.
At the same time or sometime thereafter, the Committee […] will initiate temporary reserve-draining operations aimed at supporting […] increases in the federal funds rate…
[…] the Committee's next step in the process […] will be to begin raising its target for the federal funds rate…
Raising rates by making them sufficiently scarce
21
Fixed-quantity reverse repurchase agreements (RRPs) A traditional tool How does it work? In tri-party repo system, investors give
cash to the Fed and we give them Treasury securities as collateral (essentially, a collateralized loan to the Fed)
Fixed-quantity term-deposit facility (TDF) A relatively new tool How does it work? Banks can place a fixed amount of
their reserves in the TDF, reducing their available reserves These tools change the composition of the Fed’s balance
sheet but not its size Every $1 in RRP or TDF reduces reserves by $1
Potential draining tools

Draining is less practical as reserves increase
24
Policy Normalization Principles and Plans (Sept 2014) In light of the changes in the SOMA portfolio since 2011 […]
some aspects of the eventual normalization process will likely differ from those specified earlier
During normalization, the Federal Reserve intends to ▫ move the federal funds rate into the target range set by the
FOMC primarily by adjusting the [IOER].▫ use an overnight reverse repurchase agreement (ON RRP)
facility and other supplementary tools as needed to help control the federal funds rate.
Why use the ON RRP? Isn’t IOER enough?
Raising rates through arbitrage
25
If banks can earn 0.50% (or 50 bps) leaving money in their Fed account, they won’t have an incentive to lend it out below that rate Should provide a floor on interbank rates
Absent frictions, we would expect competition to pull other market interest rates close to IOER Banks earn arbitrage profits when they borrow reserves at a
rate below IOER and earn IOER on these reserves Competitions should drive arbitrage profits to zero
In practice, money market rates did trade well below IOER What is going on?
How is IOER supposed to work?

In the Fed funds market: GSEs, including FHLBs, have Fed accounts but cannot earn
interest on reserves Interbank trades occur at rates above IOER but non-bank to
bank trades occur at rates below IOER Market is dominated by non-banks lending to banks
In other money markets (eurodollar, repo) Most cash lenders in U.S. money markets are non-banks,
including MMFs, and do not have a Fed account They cannot earn IOER
Why are market rates below the IOER?
30
Two frictions could be limiting the pull of IOER: Banks face balance sheet costs related to FDIC assessment
fee and new Basel III regulation▫ No arbitrage profits: Spread between IOER and money market
rates reflects regulatory cost U.S. money market appear to be imperfectly competitive
▫ Some arbitrage profit: Spread reflects market power of banks
There is evidence in support of both frictions Banks publicly stating they want to reduce deposits Tightening IOER – ON RRP rates spread with no change in
ON RRP demand
Why doesn’t competition lift market rates?
31
IOER Fixed-rate term-deposit facility (TDF) Works like IOER but with term rates Typically needs to be offered above IOER; otherwise, why
lock up your money for longer than you need to? Fixed-rate reverse repurchase agreements (RRPs) Traditional tool with a new twist Provides non-bank counterparties with an investment
options at a fixed rate RRPs can support rate even if there is no take-up
Additional arbitrage tools

Analysis based on Martin, McAndrews, Palida, and Skeie
We build a simple model with households, firms, banks, and nonbanks
In our model: Households use the financial system to save for
consumption at a later date Firms produce consumption goods Banks lend to firm, offer deposits, and have access to IOER Nonbanks hold government debt on behalf of households
and cannot earn IOER
A framework to think about normalization
34
Absent frictions, all money market rates would be equal to the IOER
There are three main frictions: Banks face convex balance sheet costs Market for reserves may not be perfectly competitive
▫ Explains why money market rates are below IOER Banks face convex interbank monitoring costs (reserve
scarcity)▫ Explains why interbank rates are above IOER
Nonbanks do not face balance sheet costs because they are more transparent
Key Frictions
35
Households get utility from consumption when old Sell endowment to firm when they are young Save through banks and non-banks Purchase good to consume when they are old
Banks maximize profits They may experience a liquidity shock They use reserves to absorb the shock or borrow in the
interbank market Firms maximize profits Buy household endowment and use it as input for
production Sell the goods they produce to the households
A Simple Economy
36
When the supply of reserves is small Interbank market is active Interbank market frictions are high Balance sheet costs are low Because of scarcity, banks compete for reserves
When the supply of reserves is high Interbank market is inactive Interbank market frictions are low Balance sheet costs are high Banks don’t need to compete for reserves
Two polar cases
37
The tools work by affecting the two frictions that determine interest rates: Balance sheet costs: Reducing balance sheet size raises
market rates by decreasing the spread to IOER Competition: Scarcity makes banks compete for reserves;
banks must compete with the ON RRP Interbank market frictions: Increasing the interbank market
activity raises interbank market rates Assessment: TDF: Creates reserve scarcity but does not affect balance
sheet size RRPs: Create reserves scarcity and reduce balance sheet
size (if RRP rate < IOER)
How do the tools affect the frictions?
38
Yes, TDF and RRPs can help raise rates
Large reserves RRPs are more effective RRPs (but not TDF) reduce balance sheet size Creating scarcity through TDF only would require massive
drain of reserves
Do we have the tools to raise rates?
39
Welfare in our economy can be measured as the (negative of the) sum of the three frictions
TDF: Increases rates in part by increasing interbank market costs Lower welfare
RRPs: Increase rates by lowering balance sheet costs and increasing interbank costs Trade-off: Effect on welfare can be ambiguous but likely
positive when reserves are large ON RRPs also stabilize rate by absorbing liquidly shocks
How should we use our tools?

On December 16, 2015, the FOMC decided to tighten policy IOER was raised from 25 to 50 bps ON RRP rate was raised from 5 to 25 bps Target range for the fed funds rate was raised from 0-25 bps
to 25-50 bps ON RRP cap was raised from $300 billion to an amount
limited only by the value of Treasury securities held outright in SOMA and available for such operations (about $2 trillion)
Liftoff has gone very well so far Money market rates have moved in the range ON RRP demand has remained very low

Monetary policy implementation with a large balance sheet requires relying on arbitrage, rather than scarcity
Fixed-rate tools, like IOER or fixed-rate RRPs are necessary
The quantity of reserves becomes less important—No need for fine tuning
Liftoff has worked very well so far but we still have a lot to learn from future rate increases
